Studies that fall outside the Dropout Prevention review protocol or do not meet evidence standards

Cárdenas, J. A., Robledo Montecel, M., Supik, J. D., & Harris, R. J. (1992). Coca-Cola Valued Youth Program: Dropout prevention strategies for at-risk students. Texas Researcher, 3, 111–130. The study does not meet WWC evidence standards because it uses a quasi-experimental design in which the analytic intervention and comparison groups are not shown to be equivalent.
